Specication forming part of Letters latent No. 195,45 i, dated September25, 41877; application ledl March 2,1877..

To all whom it may concern Be it known that I, EDWARD KRONENBERG, of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented a new and useful Improvement in Counterfeit-00in Detecters,which improvement is fully set forth in the following specication andaccompanying drawings, in which- Figure l' is a side elevation of theimplement embodying my invention. Fig. 2 is a top view thereof. Figs. 3and 4 are central longitudinal sections'thereot. Fig. 5 is an end viewthereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a case having in its top plate two slots, ofthe gage of the coin, and an inclosed single balance, so constructedthat coins of different denominations may be weighed therebyfthespurious pieces being detected by their inability to materially de pressthe balance and roll therefrom.

It also consists of a projecting arm for controlling the balance, sothat spurious coin may be readily removed from the case.

lt also consists of guides depending from the top plate of the casebelow one or both of the slots thereof, whereby the spurious coin duringthe operation of removal will not catch under the top plate.

Referring to the drawings, A represents a case, consisting of sides A'A', top plate B, base C, open end D, and slotted end E.

In the top plate B there are two slots, vF F', which are of diiferentlengths, and adapted, say, for half and quarter dollars, and they extendend to end inthe longitudinal direction of the case.

Within the case, below the top plate B, there is mounted a balance, G,consisting of an elliptical-shaped or dishing bar, of such length as toproject beneath both slots F F', and so weighted or hung that the weightof either a half or quarter dollar applied through the respective slotand rested on the bar will depress the balance.

It will be noticed that the portion a of the balance beneath the shortslot F curves or extends slightly upward, and the portion b beneath thelong slot F' curves downward, the

free end of the balance being at the open si e D of the case.

On the weightedV portion of the bala e there is an arm, H, which issecured ther o or formed therewith, and it projects throu h the slottedend E of the case, so as to be re ily handled. t

From the top plate B, and beneath t e walls of the slot F', there dependtwo ve ically-extending bars, J, which flare, the wid t part beingbelow.

The operation is as follows: If a genui e half-dollar is placed throughthe slot F', or a genuine quarter-dollar through the slotF, it will restcircumferentially on the balance. a d it overcomes the latter, so as tocause it to scend and assume such position that the co n will rolltherefrom and escape through t e open endD of the case, wherebyitsgenuinene s is established, after which the balance retur s to itsnormal position.

Should a spurious half-dollar be placed n the balance, the latter willnot materially scend, and the depression or downward curv ture of theportion b of the balance preven s the spurious piece rolling therefrom,where y it projects sufciently above the top plate o indicate itsnature. The same is true of a sp rions quarter-dollar, only that it willroll in o the portion b of the balance and project u ward through theslot ofthe larger piece, tl e result and indication of which being similr to that stated of the larger piece.

.ln order to remove the spurious pieces t e arm H will be held so as torender the balan e immovable, whereby said pieces may be rea ilydgraspedby hand, or the arm will be raise whereby the balance descends and thepiec s roll therefrom through the opening D of t case.

It will be noticed that the same balance employed for weighing coin ofdifferent d nominations, the operation depending up the introduction ofthe coin into the prop slot of the case.

As spurious pieces depress the balance to limited extent, and they areliable to catc under the top plate, the bars J are employe to preventthe same, their service being to d rect or guide the pieces into and tipthrongf the slot F', whereby they are readily accessibleLl It is evidentthat the slots F act as gages beneath both slots', and having anupwardlyextending portion, a), and downwardly-extending portion b,substantially asand for the purpose set forth. v

2. The case and balance,r in combination with an arm, H, secured to thebalance and projecting through the case, substantially as and for thepurpose set forth. l,

3. The case with a slotted top plate and the balance, in combinationwith depending guiding-bars J, substantially as and for the purpose setforth.
